Referring to the embodimentof the invention shown in FIGS. 1-7,association with anessentially conventional bath tub it) having theusual drain opening 12 and overflow opening 14, there is provided thehydrotherapy equipment of the invention which comprises generally a headunit 16, a pump housing 18, an electric motor 26 adapted to drive shaft22 which in turn drives the pump impeller within housing 18, and a flowconduit system comprising manifold 24, conduit 26 which provides fortwo-way flow between manifold 24 and pump housing 18, conduit 28 adaptedto interconnect manifold 24 to waste when the tub 1% is being emptied,and overflow conduit 30 adapted to interconnect the overflow opening 14with conduit 28 so that excess water entering the tub will be directedto waste. The pump housing 18 and the motor 20 mounted thereon areappropriately supported outside of the tub, as by legs 32 (FIG. 5) whichengage floor 34 (FIG. 2). In FIG. 2, the pump housing and motor areshown as being located within a space 36 which is enclosed at the top bya permanently positioned cover member 38 and a removable louvered covermember 40, the latter enabling the circulation of air into and outofspace 36 to cool the motor and enabling access to the motor and therelated parts of the equipment disposed within space 36.

The head 16 is provided with an internal inwardly and outwardly openingsleeve 42, a valve seat 44, and an open ended nozzle member 46, thelatter having external threads in engagement With internal threadsformed in sleeve 42 and being provided with a multi-fingered handle .48whereby the nozzle 46 may be rotated by hand or foot in one direction tomove it inwardly of the sleeve 42 or in the other direction to move itoutwardly of the sleeve 42 to thereby control the fiow of water throughsaid nozzle. When the nozzle 46 is moved fully inwardly of sleeve 42,its inner end is brought into engagement with the valve seat 44 toprevent discharge flow from the nozzle, and when the nozzle 46 is movedoutwardly away from seat 44, the discharge flow from the nozzle isincreased.

The head 16 is providedtwith means for entraining air in the waterissuing from nozzle 46 in a greater or lesser degree, saidsrneanscomprising a tube 50 having its lower end communicating with chamber 52.defined within the head and having its upper end provided with arotatable cap 54 having one or more openings 56 adapted to be broughtinto and out of communication with one or more corresponding openingsformed in the side of the upper end of tube 50, and air port 53 (FIG. 2)formed in the internal wall 60 of the head and providing for the passageof air from chamber 52 into the chamber 62 defined between the nozzle 46and the sleeve 42, and one or more air ports 64 enablingrthe inductionof air from chamber 62 into the nozzle 46 by the water passing throughthe latter.

The head 16 is further provided with the dependent sleeve 66 which fitsover the tubular upper end of a valve member indicated generally at 68.The lower or valve control portion 70 of the valve member 68 issupported for rotation by the surface 72 of manifold 24. The head 16 issupported on compression spring 74 (FIG. the latter being in turnsupported on flange 76 of valve member 68. Complemental means 78 securethe head 16 to the valve member 68 so that rotative movement of theformer is imparted to the latter. A manually operable spring-urgeddetent 80 (FIG. 2) having a reversely turned operable end extendingthrough sleeve portion 66 of head 16 and engageable underneath theflange 82 of annular screen member 84, the latter having its lower end86 secured within the drain opening 12, serves to releasably secure head16 at a predetermined height above the bottom of the tub 10.

The manifold 24 has defined therein (see FIG. 3) a low pressure chamber88, a high pressure chamber 90, a main passageway 92 communicable withdrain line 28, and an auxiliary passage 94 which communicates with drainline 28.

The conduit 26 has defined therein passageway 86 which interconnects theeye, or inlet, portion 98 of the pump impeller with the low pressurechamber 88 of manifold 24 and with the conduit, or passageway, 92 (FIG.3), and conduit 26 has further defined therein a passageway 100 whichinterconnects the outlet, or high pressure, side of the pump with thehigh pressure chamber 90 of manifold 24.

Assuming that the bath tub is semi-filled with water, preferably to alevel above the nozzle 46, the space within the head 16, the conduit 26and the pump housing 18 will be likewise filled with water, the inputwater to the tub entering these spaces by way of the inlet grill, orscreen,

' 84 and the space defined between said grill and the valve element 68,said latter space being in communication with the low pressure chamber88 of manifold 24 and passageway 96 of conduit 26.

Upon energization of motor 20, the pump delivers pressurized waterthrough passageway 100 of conduit 26, into high pressure chamber 90 ofmanifold 24, from chamber 90 through port 102 (FIG. 6) and into theinterior of the upper tubular portion of valve element 68, from thevalve element 68 into head 16, and then out of the unit as therelatively high pressure submerged stream through nozzle 46. The cycleof water circulation is completed by flow of the water through the grill84, the low pressure chamber 88, the passageway 96 of conduit 26, andthe eye, or suction side, 98 of the pump impeller. A removable andreplaceable Web 104 of filter material is positioned at the inner sideof grill 84 and serves the purpose of filtering the water which passesfrom the tub to the pump.

As previously indicated, the user of the equipment may control the rateof delivery of water into the tub by the pump by adjusting the nozzle 46and he may control the amount of air entrained in the Water streamentering the tub by adjusting the air control cap 54 on air tube 50.Also, as previously indicated, the user may vary the angular position ofthe nozzle 46 relative to longitudinal axis of the tub by rotating thehead 16. Foot control means for this purpose are provided in the form offoot bars 106 which are integral with the head 16 and extend laterallytherefrom. A range of angular swing of head 16 of about 45 in eachdirection away from the longitudinal axis of the tub is adequate toprovide the user with any desired flow pattern within the tub.Throughout this total of 90, and even more, of angular variation of thehead 16 for practical use of the unit, the port 102 of valve element 68will have a sufficient degree of communication with the high pressurechamber 90 of manifold 24 so that the rate of flow of the high pressurestream out of the nozzle 46 for any given setting of the nozzle will beessentially unvaried. In other words, the flow space defined between theinner end of the nozzle 4 46 and the valve seat 44 is the limitingfactor determining the rate of outlet flow through the nozzle for anygiven setting of the head throughout the about range of adjustment ofthe head for practical use.

While the chamber 92 is in communication with the low pressure chamber88 of manifold 24 and the suction passageway 96 of conduit 26, gatevalve 103 (FIG. 2) closes off the chamber, or passageway, 92 fromcommunication with the drain line 28 during normal use of the unit.While the passageway 94 of manifold 24 is in communication at all timeswith the drain line 28, communication between the passageway 94 and thelow and high pressure chmbers 88 and 90 of manifold 24 is prevented byvalve element 63.

In the event that the user continues to fill the tub with water throughthe tub feed faucet 110 to the point where the water level in the tubreaches the tubs overflow opening 14, the overflow of water will passthrough the opening 14, down tube 39, through apertures 112 in the upperside of gate valve 108, through the open lower end of the hollow gatevalve element 108, through port 116 in manifold wall 118, intopassageway 94, and from the latter into the drain line 28 and throughthe trap 120 to waste.

After a desired period of use of the unit, the user need merely rotatethe head 16 through 180 so that the outlet of the nozzle is directedtoward the adjacent end wall of the tub. Before this degree of swing ofthe head 16 is completed, the port 102 of valve element 68 is broughtcompletely out of communication with the high pressure chamber 90 ofmanifold 24, thereby shutting off pressurized flow to the nozzle andbringing the high pressure chamber 90 into communication with passageway94 through undercut port 122 (FIGS. 6 and 7) formed in valve element 68and port 124 formed in the manifold 24. Continued operation of the unitin this condition serves to pump the water from the tub and into thedrain line 28 to waste. Means hereinafter described are provided todeenergize the motor 20 after the water level in conduit v26 andmanifold 24 has been lowered to a predetermined degree. When thisoccurs, the conduit 26 and the manifold 24 are brought intocommunication with the drain line by the raising of the gate valve 108,the latter operation being effected by manual rotation of the controlarm 126 affixed to crank lever 128 to thereby raise rod 130 and the gatevalve 108 carried thereby.

When the entire system has been drained through the drain line 28, savefor the relatively small amount of residual water within passageway 94,the unit is conditioned for subsequent use by dropping the gate valve108 to the position of FIG. 2 and by rotating the head 16 to interruptcommunication between chamber 90 and passageway 94 and bring the port102 of valve element 68 into communication with chamber 90. The residualwater within the passageway 94 is then fully blocked off from access tothe hydrotherapy unit or the tub and it will be flushed from the systemthrough the drain line 28 at the end of the next session of use of theunit, i.e., when the next charge of water within the tub is pumpedtherefrom through the passageway 94 in the manner above described.

In FIG. 8 there is exemplified a control system for the hydrotherapyunit. Lines 132 and 134 furnish line voltage for the operation of thepump motor 20, the motor being actuated upon operation of the relayindicated generally at 136 and comprising coil 138 and switch contacts140 and 142. The relay 136 is controlled by a control circuit indicatedgenerally at 144.

The control circuit 144 further comprises switch 148, a master controlswitch 152, and a pressure-sensitive switch 154, the latter beingmounted within the high pressure passageway 100 of conduit 26.

Switches 148 and 152 are desirably positioned on a walllocated faceplate of an outlet box which is positioned adjacent to the tub 10. Theswitch 148, although not so amasao illustrated, my be of the timer typeadapted to be closed to be closed for varying selected periods of timein accordance with the desire of the user as to the particular length oftime the hydrotherapy equipment is to be used. Prior to entering thetub, the user of the equipment operates switch 148. Switch 152 ispreferably of the type which requires a key to operate, and thereby theprovision of switch 152 places the operation of the hydrotherapyequipment under the control of the possessor of the key for theoperation of this switch. This is not only desirable in motel and hotelinstallations to insure that the unit will not be used by someone notauthorized to do so, but it is also desirable in connection withresidential installations in order that those in authority may controlthe extent and time of use of the equipment.

After the switches 14% and 152 have been closed, the user commences thefilling of the tub with water. When the water level has risen above thenozzle 46, the static pressure of the water applied to thepressure-sensitive switch 154 causes said switch to close and therebycnergize the motor 2% and the pump driven thereby. Dur ing the time thepump is operating, the switch 154 is sub jected to a dynamic pressurecondition, and switch 154 is sufiiciently sensitive to this condition toremain closed during the power draining of the tub until the water levelwithin passageway of conduit 26 has dropped a substantial degree withinsaid passageway.

In FIGS. 9-11 there is shown a somewhat simplified embodiment of thehydrotherapy equipment of the invention. Here, the tub 216 is providedwith the drain open ing 212 and with an overflow opening whichcommunicates with a downpipe 214. A face plate 215 slotted at itsunderside for the admission of overflow water to pipe 214 is secured tothe pipe 214 through the overflow opening. The head 216, similar to thatpreviously described, has a sleeve 217 at its underside which isdisposed in telescoped relation to valve tube 218, the head beingsupported by head base 220 which has an externally threaded sleeveextension 221, the latter being threadedly engaged with and supportingthe manifold 222. To the lower end of manifold 222 there is secured, asby bolt ing, a valve seat member 224 having a conduit extension 225which is connected to the downpipe 214.

The head base 220 is provided with a lateral slotted portion 228 overwhich is removably placed filter pad and retainer screen means indicatedgenerally at 230.

The head 2116 is provided with a key, not shown, which fits within avertically disposed slot, not shown, in valve tube 218, thereby securingthe latter to the head 216 for rotative movement with the head. The headis also provided with a lock control button 232 which is adapted tooperate a spring-urged tang, not shown, to lock the head to the headbase 225) by engagement of said tang beneath the inwardly directed upperflange portion 234 of head base 220.

The lower end of tube 218 is provided with inflow slots 236 and 238, andthere is secured to the lower end of the tube 213 by means comprising aU-shaped yoke 249 a valve elemcnt 242. The arms of the U-shaped yoke aresecured to the exterior of the tube 218, and the upper ends of thesearms serve as a seat for compression spring 244, said spring reactingagainst the manifold partition 246 to urge the valve 242- against thevalve seat 248.

Manifold partition 246 divides manifold 222 into a suction compartment253 and a pressure compartment 252, both of said compartments being incommunication with separated passageways in the conduit 254. The outputside of the pump disposed within housing 256 communicates with thepressure chamber 252 and the input side of the pump communicates withthe suction chamber 250; Pump motor 258 is mounted on pump housing 256.The load constituted by housing 256 and motor 253 may be borne byconduit 254 through the flanged connection 260 between conduit 254 and amatching con duit 2&2, forming part of the pump housing 256.

It will be appreciated that the path of flow of the water is as follows:Inwardly of the lateral slotted portion 228 of head base 220; downwardlythrough the sleeve extension 221 of the head base and into the suctionchamber 250; from suction chamber 250 through communicating low pressurepassageways in conduits 254 and 262 to the eye of the pump impeller;outwardly from the periphery of the impeller to communicating highpressure passageways in conduits 262 and 254 to high pressure chamber252; through slots 236 and 238 formed in tube 218; upwardly through tube218 to the head 216; and out of the nozzle element of head 216.

To drain the tub, the head 216 is turned so that the outlet of thenozzle is directed toward the adjacent end wall of the tub. Thismovement is imparted to tube 218 and by the tube to the valve element242 to rotate the latter from its covering relation to the valve opening248. The subsequent liow of water from pressure chamber 252 will bethrough the valve port 248 to line 226 and then downwardly throughdownpipe 214 and through trap 264 to waste. It will be appreciated thatthe entiree part of the discharge conduit system is drained to waste.

It will be further appreciated that it is not necessary to drain the tubby means of the pump, either with respect to the modification of FIGS.9-11 or with respect to the embodiment of the invention shown in FIGS.1-7. The system can be gravity-drained by actuating the on-otf switch todeenergize the pump motor and pump. In such event, gravity draining willresult from a rotation of the head to direct the nozzle outlet towardthe adjacent end wall of the tub. 4

A further modification oi the hydrotherapy equipment of the invention isshown in FIGS. 12-14. With respect to this modification, only thosefeatures. will be mentioned which are different from those of themodification of FIGS. 9-11.

The essential ditierence between these two modifications is that the oneshown in FIGS. 12-14 has the pump housing 356 and the pump motor 358inverted and mounted beneath the tub in depending relation to themanifold 322 and the low pressure conduit extension 364 which is madeintegral with the manifold 322 and that part of the housing 356 in whichthe pump impeller 366 resides.

Inflow from the tub to the pump impeller takes place through the headbase 329 and the low pressure conduit 364. Outflow from the impeller isreceived by chamber 368 in housing 356 and passes into manifold chamber352, after which the path of movement of the pressurized water is thesame as that described in connection'with the modification of FIGS.9-11.

The parts or elements of the embodiment of the invention shown in FIGS.12-l4 which correspond toor are identical with the parts or elements ofthe embodiment shown in FIGS. 9-11 are designated by correspondingreference numbers to which 100 has been added.

It will be noted that in the embodiment of FIGS. -91l the pump housing256 is provided with an air vent line 263 which is in communication withthe upper end of the overflow pipe 214. The positional arrangement ofthe pump with respect to the components of the conduit system externalto the tub call for the pro-vision of such an air vent line in order toprevent the pump from becoming air locked during the course of asubsequent introduction of water into the tub. On the other hand, thepositional arrangement of the pump with respect to the water conduittree in FIGS. l214 is such that the pump cannot become air locked, andhence no air Vent line is suggested for this last-described embodiment.

While a number of embodiments of the invention have been shown anddescribed, it is to be understood that the hydrotherapy equipment of theinvention is subject to considerable change and modification from thestandpoint of both the skill of the art and that of the rule ofequivalency, and that the scope of the invention is to be appro- 7priately construed in the light of this and the appended claims.
